Only PIT, IRQ and reset can bring the MCU from LPSTOP.</P><P>The stop bits can put individual modules into Stop mode without LPSTOP instruction. <BR />2. GPT doesn’t wake up.</P><P></P><P>Regards,</P><P>Daniel</P></BODY></HTML> Sun, 30 Sep 2018 21:06:46 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MC68HC16Z1-behavior-in-LPSTOP/m-p/818343#M15880 danielmartynek 2018-09-30T21:06:46Z
